Base officials said they found traces of the pollutant in tests at the fort’s southern boundary.

The material is known as Royal Demolition Explosive. The U.S. Centers for Disease Control and Prevention say the chemical compound can cause seizures in people who swallow a lot of it.

It has been tied to cancer in laboratory animals and is considered a possible cancer-causing material for people.

South Carolina Department of Health and Environmental Control Director Catherine Templeton said her agency plans to meet with Army officials to discuss what to do about the pollution.

There was no information on when the meeting would occur.

Army officials said the amounts of the chemical found in groundwater were less than health advisory levels established by the U.S. Environmental Protection Agency.

The fort said private wells will be tested the first two weeks of next month, with property owners’ permission. The fort also plans to have town hall meetings for those living within a two-mile radius of the base.
